WIRE-COILING MACHINE.-

SPECIFICATION forming part of Letters Patent No. 456,512, dated July 21, 1891.

Application filed August 26, 1890. Serial No. 363,090. (No model.)

To all whom it may concern:

Be it known that I, CHARLES A. HART, a citizen of the United States, residing at Chicago, Illinois, have invented certain new and useful Improvements in vire-Ceiling Machines, of which the following is a specification.

The object of my invention is to make a machine for ceiling wire for different purro poses and automatically cutting off the coils as the wire is drawn through; and my invention consists in the features and details of construction hereinafter described and claimed. i 5 In the drawings, Figure l is a plan View of my improved wire-coiling machine. Fig. 2 is a. side elevation of the same. Fig. 3 is a vertical section taken through the line a of Fig. 1, looking in the direction of the arrows. Fig. Ll is a vertical sect-ion taken in the line I) of Fig. 1, looking in the direction of the arrows. Fig. 5 is a rear elevation of the automatic cut-olf. Fig. 6 is a plan View of the same, taken in the line g of Fig. 5, looking in the direction of the arrows. Fig. 7 is a rear elevation of thc automatic cut-off immediately after the cutting operation; and Figs. S, 9, and 10 are details of parts used in the cut-off.

In making my improved wire-ceiling machine I arrange the parts on a suitable bench or table A and support them in brackets or standards or other suitable frame-work. I mount on the table, in suitable supports, a pulley B, adapted to receive a belt and to be rotated by any convenient motive power. The shaft of this pulley carries a pinion C, which engages with a gear D on a shaft D', arranged in suitable supports on the table, so that as .the pnlley-shaft is rotated the shaft D :may also be rotated.

At a convenient point on the shaft D', but preferably near the end, I arrange a pair of disks E, which may be beveled on their edges,

as shown in the drawings, or not, as may be desired. These disks are adj ustablc lengthwise of the shaft D', so that they may be arranged opposite 'the point in the coiling-shaft (hereinafter described) desired, and are held in the proper position, preferably, by means of nuts, as shown in Fig. l. They are also adjustable with respect to each other by interposin g a washer between them, so that they may be held closer together or farther apart,

as may best adapt them to wires of diiferent size or gage, as may be necessaryin making the coils of one size of wire or another. By adjusting the disks on the shaft D with respect to the ceiling-shaft, so as to be nearer to or farther from a point opposite to that 6o from which the wire is fed onto the coiling shaft, the pitch of the coil may be varied or determined, and by adjusting them closer to or farther from each other different sizes of wire maybe accommodated. As these disks are simply intended as the 4means for drawing the wire onto the coilingshaft, they may be modified or other means employed in their place, as desired. Unless specifically mentioned in the claims, I do not 7o wish, therefore, to confine myself to disks only for drawing wire onto the coiling-shaft. A knuckle-joint F is arranged at the end of the pulley-shaft, and an adjustable link F is ar ranged between such kn tickle-joint and a knuckle-joint G on the end of the mandrel or coiling-shaft G. This coiling-shaft is arranged on a pivoted vertically-adjustable support II, carrying a bracket II', which affords the journals in which the ceiling-shaft 8o G rotates. The support II is vertically adjustable through means of the bolts 71., so that the coiliug-shaft may be vertically adjusted to the pitchof the particular style of coil being made, so that the wire of the coil will be kept parallel with the disks E. The bracket H is also adjustable in its horizontal plane on the standard H, which connects it to the pivoted support lI. lhe object of this horizontal adjustment is to permit coils of diier- `9c ent diameter to be made on the same mandrel by causing the wire either to pass directly or diagonally around it. The wire is drawn in through tension-rollers I by means of the disks E, which bear against the sides of the wire and draw it through as they rotate. The tendency of the wire as it coils around the shaft G is to draw such shaft away from the disks, and to prevent this I have arranged a spring J, connecting an arm j, preferably roo fastened to the supports of the shaft D', with a rod j", extending up from the bracket H.

means of a nut, as shown in Fig. l, so that its tension may be regulated to the kind ol wireA being worked into coils, so as to constantly hold the coiling-shat't in its proper relation to the disks.

In order to automatically cut ott the wire as the coils are formed, I arrange a gage K in such position that the wire ot' the coil will come against it whenever it has attained the desired length. As the wire is coiled around the mandrel it is constantly advancing forward, and in beginning the operation the end of the wire is passed through a hole in astnd or pin L, supported and held in proper position in any convenient manner. A sleeve or collar L', to operate as a cutter, is arranged around the pin and provided with an arm Z, extending out from it a desired distance. At the end of this arm is pivoted a cam IWI, provided with extending` arms m and m. A wire or rod M extends from the gage K to the cam M and engages with one of the arms m of the cam,.but in a waythatwill permit it to be disengaged when force is applied. Vhile it is engaged with the arm m it holdsthe cam in a position where the arm N on the ceiling-shaft does not strike or engage with it in its rotations. As soon, however, as the gage K is forced out by the pressure of the advancing coil the wire `connecting it with the cam M is also moved out, and as it moves it turns the cam M on its pivot. This brings the other arm m into the path of the arm N, rotating on the coiling-shaft. The arm N then engages with it and forces the cam M around until its arm m YhasV been moved out of its path. This causes the other arm m, with which the rod from the gage K was engaged, to be thrown around, so as to move the arm Z enough to allow it t0 pass its end, as shown in Fig. 7. As the arm Z is thus thrown around it throws the cutter L around the stud L into cutting position, so as to cut off the wire passing through the hole in the pin. A spring Ois arranged to instantly throw the arm Zand the cutter back into their initial position and to permit the wire to continue its advance through the hole in the stud. As the arm N again comes around in the rotation of the coiling-shatt it strikes one of the arms m and carries the cam again around enough to force one of its arms m into engagement with the rod extending forward to the gage, which has been again brought into its original position by the spring O', so as to be in readiness for another operation when the coils of the wire have again pressed the gageout. In this way, as the wire always engages with the gage after the same number of coils have been formed and as the gage is moved out under the same pressure each time, I am able to cut off the coils at substantiallya uniform length and to perform the cutting operation automatically.

Nothing is required after the machine is set in operation 'but to supply it with wire,

which is furnished from a reel,to continue the operation of forming and cutting oft' the coils as long as desired. There it is desired to make the coils either open or closed or to change the degree of openness by changing` the pitch of the coil, all that is necessary is to adjust the tensionrollers I in the one direction or the other, as provided for by the bolt I', so as to supply the wire to the mandrel from thc proper position to secure the pitch desired.

Of course various modifications may be made in the forms and details of construction of the parts that enter into my improved coilingmachine. As an example of such modications, I would saythat the ceiling-shaft G need not be made as long relatively as it is shown in the drawings, nor need it be in the shape of a stepped cone, as shown, but may be made of any length and shape desired to ad'mit of the wire being turned around it to form the coils. In like manner mechanical changes in the construction and arrangement of other parts can be introduced, as may be Jfound convenient or desirable. I therefore do not desire to limit myself to exact details of constructiomexcept as the same may bey specified in the claims.

W'hat I regard as new, and desire to secure by Letters Patent, is
